A primary function of cholesterol in the plasma membranes of some animals is to A) make the membrane more rigid, allowing it to resist pressure from outside the cell. B) facilitate the removal of hydrogen atoms from saturated phospholipids. C) facilitate cell-cell interactions by binding to receptors on neighboring cells. D) enable the membrane to stay fluid more easily when the temperature drops.

The presence of cholesterol in the plasma membranes of some animals Connects cells to each other and allows them to communicate. Enables the membrane to stay fluid more easily and adds structural support. Enables the animal to add hydrogen atoms to unsaturated phospholipids. Enables the animal to remove hydrogen atoms from saturated phospholipids.
Which of the following is true about cholesterol? (A) $\quad$ Cholesterol always increases membrane fluidity in cells. (B) $\quad$ Cholesterol is a steroid hormone precursor (C) $\quad$ Cholesterol is a precursor for vitamin $A,$ which is produced in the skin. (D) $\quad$ Cholesterol interacts only with the hydrophobic tails of phospholipids.
